B.J. Raji, Boston CollegeThe Good: A thick, low-built tackle with excellent lower body strength and power on contact. Has a great first step for his size and really gets into offensive linemen quickly. Displays impressive base strength to hold the point of attack against the double-team or push the pocket. Uses his strong leg drive to bull-rush defenders and showcases excellent suddenness and a good rip to get off blockers. The Bad: Is a bit short by NFL standards and lacks great lateral mobility in space. Has shorter arms and allows too many linemen to get in on his chest. Lacks straight-line speed and isn't much of a factor on the perimeter.

Positives: Very strong. Drops anchor and is not easily moved. Able to generate a surge and re-establish the line of scrimmage in the backfield. Has strong hands to punch, shed and play off blocks. Displays good short-area quickness for a man his size. Feels pressure and finds the ball while maintaining good balance - he's seldom on the ground. Can club, swim and rip effectively to free himself up. Showed well in one-on-drills during Senior Bowl practice and was disruptive in team drills.Negatives: Short and short-armed. Does not have great hip snap or flexibility to overpower blockers early or win one-on-one battles with creativity. Thinks he is better than he is. Conditioning and stamina are concerns. Was inconsistent before his senior season and his weight has fluctuated. Much of sack production came when he was unblocked. Immature upon arrival in college and motivation must be closely evaluated.Summary: Stout, big-bodied run-stuffer with natural girth. Showed enough quickness to beat up on weak ACC competition but has some pass-rush limitations that could relegate him to the first two downs at the next level. Possesses the raw strength to anchor a "30" front or play the nose in a 4-3. Scouts have compared him to Sedrick Ellis, who also did not use his hands well, consistently play low or explosively rush the passer. But when both are on the field, they will command extra attention that will free up the rest of the line.Grade: First-round talent.
